This invention relates to collapsible tubes for containing and dispensing tooth paste, shaving cream, or the like, and more particularly to a clip for locking the fiat end of such 6 a collapsible tube.

One object of this invention is to provide a paste tube clip which will be very securely attached to the fiat end of the tube and yet will not pierce or puncture the metal thereof.

A further object is to provide a device of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, rigid, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view there have been illustrated on the accompanying drawing several forms in which the invention may be convenientlyembodiedin practice.

Fig. 1 represents a plan view of a collapsible tube having applied thereto a clip of the first formembodying the invention.

Fig. 2 is a plan View on an enlargedscale of a portion of the clip shown in Fig. 1.

Fig. 3 is an interior end View of the same. .Fig. 4 is a side sectional view taken along the line H of Fig. 2.

Fig. 5 is a plan View of a modified form of clip having a pair of staggered indentavf tions at each end thereof and providing a space between said indentations for receiving printed matter.

Fig. 6 is a plan view of a modified form of clip, similar to the clip shown in Fig. 5

"- but employing three indentations at each end thereof.

Fig. 7 is a plan view of a modified form of wide clip adapted to be used on large tubes. 1

It has been customary in the past to secure the locking clips of collapsible tubes in position on the flatrends of such tubes by means of cooperating sets of indentations in the clip situated opposite each other. One

indentation of each set was generally a point and the other indentation a socket fitting about said point. It was found in practice, however, that this form of construction was easily bent out of shape and was quite apt @5359 to puncture the soft metal of the tube. It

was also expensive to manufacture such clips. means of the presentinvention' the above and other disadvantages have been avoided. This has been accomplished by providing a locking clip having the indentations on'theopposite sides;thereof out of alinement with each other, or staggered. The indentations are elongated to provide stiffness for preventing bending, and the adjacent ends thereof are located sufiiciently close to grip the metal of the tube securely but without danger of puncturing it. In addition, this construction is much cheaper to manufacture than the former types of clips, Referringnow to the drawingin which like reference numerals denote corresponding parts throughoutthe several views, the nuineral 10 indicatcs a collapsible tube'for containing paste to be dispensed through a neck 11, after the cap 11 is removed, by squeezing the cylindrical part 12 thereof. The end 13 of the tube oppositefrom the neck 11 is Hat and is adapted to be locked'by a U-shaped clip 14 having opposing substantially parallel sides 15 and 16. Extending inwardly frombo'th sides15 and 16 are a plurality of ;j-equ ispaced indentations 17, 18, 19 and 20,21,

"22, respectively. As most clearly shown in Figs. 2,3, and 4:, each of the indentations is elongated andof substantially rectangular form having rounded ends and being slightly pointed or tapered in orderto forina secure grip upon the metal of the tube locatedtheree w v I 1 p I Iiithe modified form of clip 22 shown in Fig. 5, a pair of opposed cooperating indentations 23, 24 and 25, 26 areprovidedfatthe "ends only, leavingasection 27 therebetween on which any desired lettering=may be stamped. i In Fig. 6 another modified form "of the invention isshown, this clip28 being similar to the clip of Fig.5 with tliefexceptionthat three cooperating indentations 29,30, 31 and 32, 83, 3e are provided at the ends of the clip28, 1 i w A stillfurtherniodified form of locking clip 35 is illustratedin Fig. 7; This clip is made considerablywider and longerthan the first form shown inFig land instead of six alternating staggered indentations, theclip shown in Fig. 7 has nine of such indentations numbered 36, 37, 38, 39, 40, 4 1, l2, i3, 44;, respectively. i V a V v VVhile there have been disclosed in this specification several forms in which the in vention may. be embodied it 'is-to beiunde'rstood that these forms are shown forthe pure f in various other forms without departing, i
